This week saw the premiere of the sixth episode of the fifth and final season of Fox’s “Gotham,“ but it’s next week’s Episode 7 that promises to really get everyone talking.

Next week, it looks like Jeremiah Valeska is finally going full Joker.

In “Legend of the Dark Knight: Ace Chemicals”…

Gordon races to uncover the criminal element threatening to end talks of Gotham’s reunification with the mainland. A very much alive Jeremiah returns and organizes a twisted recreation of the murder of Bruce’s parents with the help of Jervis Tetch aka Mad Hatter.

Witness Jeremiah’s final act of insanity on Thursday, February 21st.
